Bis{4-bromo-2-[(2-hydroxyethyl)iminomethyl]phenolato}nickel(II) monohydrate

Abstract

The title mononuclear nickel complex, [Ni(C9H9BrNO2)2]·H2O, was obtained by the reaction of 5-bromosalicylaldehyde, 2-aminoethanol and nickel nitrate in methanol. The NiII atom is six-coordinated by two phenolate O, two imine N and two hydroxy O atoms from two crystallographically different Schiff base ligands, forming an octahedral geometry. In the crystal, molecules are linked by intermolecular O—H...O and O—H...Br hydrogen bonds, forming a three-dimensional network.
